This is an important issue and thanks for highlighting the swamp ass issue, which for me is a total turn off. The main reason why we shower before a massage or before massaging someone is to ensure we are sexcitingly palatable for engagement. The musty smell and bodily residues on hole and pubic regions need to go before a massage. A masseur needs fresh meat; not a month old carcass ... people wipe wipe wipe before you get swiped... ??
